One of three disgraced lawyers busted in a massive real estate Ponzi scheme pleaded guilty today to essentially being the plot’s putz — helping his co-defendants steal $31 million but hardly pocketing a penny.

Peter Vogel, 70, drew about $300,000 in salary over the three years he helped dupe some 100 investors into shady buy-and-flip property deals, but otherwise made no money in the scheme, said his lawyer, Michael Bachner.

Vogel will serve five years probation and 3,000 hours of community service working at a nursing home near his home in Bergen County, Bachner said.

Vogel and his co-defendants and former law partners Joseph Greenblatt and Joseph Mongelli promised investors 12 percent interest or better through their shady company, Maywood Capital, prosecutors said.

Charges are still pending against Greenblatt and Mongelli — who was city council president in Elmwood Park, Bergen County, when he was arrested in 2007.
